Supermicro psu and gigabyte motherboard problem

Hi there,

I have a supermicro chassis and redundant power supply, along with a Gigabyte GA-EX58-UD4P mother board, and an i7 920 CPU.

When I go to boot the computer all i get are sort beep which keep going.
Tried powering up with another psu and no beeping.

I did a little more reasearch and started metering the psu outputs. I found that both were identical except that the super micro did not have a -5v line, jsut an empty whole.

Does someone on here have a better idea as to what the deal is with the -5 line? looking at Wikipedia, they suggested that the -5v line is no longer used and is optional....

turns Supermicro motherboards do not require -5v....

Do I have any other options other than going with a supermicro board?

  1. What PSU are you using? How many amps does it have on the 12V rail(s)? What are the rest of your specs?
  2. The ATX 2.0 specifications did away with the -5 volt output.
